SpaceX Super Intelligence has bundled X Premium, Grok, and Cursor into a single subscription called The X Subscription, with five tiers: Free, Plus ($8/month), Premium ($30/month), Super ($100/month), and Ultra ($200/month). AI usage limits scale with tier; the free tier includes only limited chat and agent usage, and the latest Grok models require Premium or above. Existing users can upgrade from their X subscription settings, with the option rolling out gradually.
